PTX cvt syntax changed, not documented correctly in PARALLEL THREAD EXECUTION ISA VERSION 3.1 #5

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
When emulating MVSCMP.exe, the parser halts on a CVT instruction: 
cvt.f32.f64.rn %f141,%fd163;

Basically, it's with syntax that not documented in the PTX ISA guide.

Fixed in r153.  The parser was updated.
